IT has previously been shown1,2 that when rat thymus cells are incubated in the presence of glucose labelled with carbon-14, the isotope is incorporated to a different extent in the ribose ...

DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

Due to its deoxyribose sugar, which contains one less oxygen-containing hydroxyl group, DNA is a more stable molecule than RNA, which is useful for a molecule which has the task of keeping genetic ...

In natural life on Earth, the nucleic acids DNA and RNA are formed by sugar molecules — deoxyribose in DNA and ribose in RNA — that link to phosphates to form a backbone onto which the four ...

Later it was found that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and DNA. In 1943, American Oswald Avery proved that DNA carries genetic information.

Due to its deoxyribose sugar, which contains one less oxygen-containing hydroxyl group, DNA is a more stable molecule than RNA, which is useful for a molecule which has the task of keeping genetic ...

Ribose, a sugar needed for life, ... Other similar experiments have done the same for ribose’s chemical cousin deoxyribose, which helps form the backbone of DNA (SN: 12/19/18).

Parts of DNA can form in space. For the first time, scientists have made 2-deoxyribose, the sugar that makes up the backbone of DNA, under cosmic conditions in the lab by blasting ice with radiation.

In DNA and RNA, the sugars are deoxyribose and ribose, respectively. Holliger made new types of genetic material by replacing these with different sugars or other molecules.
